Coming from 22, I expected cursor-type to work as buffer-local variable.
That's what it's documented as, and there is no entry in NEWS  
regarding this.

However, setting cursor-type takes no effect.
Having looked at the nsfns.m code, I tried this

(set-frame-parameter nil 'cursor-type 'bar)

and voila, it does the job.

Is this intended and the same across platforms?  if so, a NEWS entry  
would be nice.  (I haven't checked the manual).
